A general rule for pleated air filters (such as those manufactured by FilterBuy) is to replace them every 90 days. As the filter accumulates more dirt, dust, and allergens from the air, its efficiency decreases. To determine if you should replace the filter more often, look for signs that your air conditioner is working harder than usual. If the unit is hot to the touch or hot air is escaping from the rear, it may be time to change the filter.
Experts recommend changing fiberglass filters once every 30 days, while pleated filters can last up to six months. For basic 1 to 3 air filters, brands generally suggest changing them every 30 to 90 days. If someone in your home has allergies, you may want to use a better air filter or change it more often. Invented in 1902 by Willis Carrier, air filters work by transferring unwanted components of air from indoor spaces to outdoor spaces.
However, if the filter becomes clogged, it will put extra pressure on your air conditioning system, resulting in poor air quality and circulation. To maintain the efficiency of your device and ensure clean air in your home, it's important to keep the filter clean by replacing it regularly. Smaller homes may require less frequent filter changes as their air conditioning systems have to move less air. Any use will cause dirt to be trapped in the filter; however, if you have a hypoallergenic pet or one that doesn't shed much hair, you may not need to replace the filter as often.
It's also important to note that spending more than 90 days without replacing the filter won't cause irreparable damage to your system. To improve air quality and stay healthy, follow proper filter replacement programs and turn your thermostat fan switch from AUTO to ON. If someone in your family has mild to moderate allergies, change the filter every 6 weeks. If changing your air conditioner filter doesn't resolve any symptoms you may be experiencing, contact a professional HVAC contractor for help. To ensure optimal performance of your air conditioning system and maintain good indoor air quality, it's important to replace your 20x20x1 air filter regularly.
As a general rule of thumb, pleated filters should be replaced every 90 days while fiberglass filters should be changed every 30 days. If someone in your home has allergies or asthma, you may want to use a better air filter or change it more often. Additionally, if you notice that your AC unit is working harder than usual or hot air is escaping from the rear of the unit, it's time to replace the filter. Lastly, if changing your air conditioner filter doesn't resolve any symptoms you may be experiencing, contact a professional HVAC contractor for help.
